Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581732, here are decompositions:

3 + 581729 = 581732
31 + 581701 = 581732
181 + 581551 = 581732
211 + 581521 = 581732
241 + 581491 = 581732
379 + 581353 = 581732
409 + 581323 = 581732
421 + 581311 = 581732

Showing the first eight; more decompositions exist.
